MACHINE FOR MAKING H OOK-HEADED NAILS.

SPECIFICATION formingpart of Letters Patent No. 300,758, dated June 24-,1884.

Application filed December 26, 1883. (N0 model.)

To all whom it may concern.-

Be it known that I, BENJAMIN BRAZELLE, of St. Louis, in the county ofSt. Louis and State of Missouri, have invented certain new and usefulImprovements in Machines for Making Hook-Headed Nails, of whichimprovements the following is a specification.

The object of my invention is to provide a machine of simple, durable,and inexpensive construction for the manufacture of nails or keepers formetallichoops of kegs, barrels, &c., of the class formed of a metallicstrip, bent and provided with either a'single or a double point at oneof its ends. Nails of such description-an instance of which may be foundin the patent of Joseph J. Heim, No. 273,076, dated February 271883--have operated satisfactorily in practice in retaining metallichoops in position on kegs and other vessels, and by my invention may beproduced with such economy, rapidity, and accuracy as to enable thedemand therefor to be supplied with promptness, and at fair andreasonable prices. The improvements by which I attain such end arehereinafter fully set forth.

In the accompanying drawings, Figure 1 is a front view, in elevation, ofa nail-machine embodying my invention; Fig. 2, an end View, inelevation, of the same as seen from the right, and with part of the feedmechanism broken away; Fig. 3, a plan or top view, partly in section, ofthe same; Fig. 4, a View in elevation of the feed-rolls and theirdriving mechanism, as seen from the right of Fig. 1; Fig. 5, a plan ortop view of the fixed die as adapted for the manufacture ofsingle-pointed nails; Fig. 6, a bottom view of the corresponding movabledie, Fig. 7, a side view of a movable die adapted for the manufacture ofdoublepointed nails; Fig. 8, a bottom view of the same; Fig. 9, a sideview of the corresponding fixed die; Fig. 10, a plan or top view of thesame; Fig. 11, a view in perspective of a single-pointed nail as formedby the machine, and Fig. 12 a similar View of a double-pointed nail. 1

In the practice of my invention I provide a stout frame, 1, in the upperportion of which is formed a bearing, '2, for a driving-shaft, 3, whichis rotated by the application of power from any suitable prime mover toa pulley, 4, upon one of its ends. A crank or eccentric,

5, upon the opposite end of the driving-shaft, is coupled by aconnecting-rod, 6, to a crosshead, 7 which is fitted to move verticallyin guides 8 on one side of the frame, and has secured to its lower sidea movable die, 9, which the nails are bent, pointed, and cut from theblank, as presently to be described. A fixed die, 10, is secured to theframe below and in line with the movable die. An angular recess, 11,corresponding in the form and dimensions of its sides with the outerlongitudinal outline of the nail to be cut, and having a cutting -edgeat the outer end of its longer side, is formed in the lower side of themovable die 9, adjacent to which recess and next its shorter side apunch, 12, having (where single-pointed nails are to be made) an angularor V-shaped face, is also formed on the die 9, as shown in Figs. 1 and6. A projection or former, 13, the sides of which are parallel to thoseof the recess 11, is formed upon the upper side of the fixed die, and atongue, 14, having an angular or V-shaped recess, 15, the sides of whichare in line with those of the face of the punch 12, is also formed on orsecured to the fixed die. (See Figs. 10 and 5.) A stop, 16, is securedto the top of the tongue 14, with the plane of its face in line with thepoint of the recess of the tongue 14:. The opposite end of the fixed die10 is faced ofi to form a bed or track, 17, which is in or about in linehorizontally with the top of the tongue 14..

The strip or blank 18, from which the nails are to be made, is fed alongthe bed 17 up to and against the stop 16, by and between a pair offeed-rolls, 19 20, the faces of which correspond, substantially, inwidth with the blank,

and are provided on opposite sides, respect-- ively, with flanges 21.The upper feed-roll, 19,is secured upon a shaft, 22, which is fitted torotate in bearings 24 25, one of which, 24, is fixed to the frame 1, andthe other, 25, formed on one end of an arm or bar, 26, the opposite endof which is pivoted by a bolt, 27, to the frame. A limited degree ofvertical movement is thereby permitted to the adjacent end of thefeed-roll shaft, to accommodate variations in thickness of the blank 18,the face of the feed-roll 19 being pressed thereto by a spring, 28, inthis case of rubber, which is compressed against the bar 26 byv a bolt,29,

and nut 30. Rotation is imparted to the feed- I roll shaft 22 by a belt,31, passing around a pulley, 32, fixed upon the driving-shaft 3, and

around a pulley, 33, on the feed-roll shaft 22,

and the lower feed-roll shaft, 23, is driven by a spur-gear, 35, uponone of its ends, which engages a similar gear, 36, on the shaft 22.

The pulley 33 is fitted loosely upon the shaft 22, and drives the sameby the friction induced thereon by a spring, 34, which is compressedwithin a recess in the pulley 33 by a nut, 35,

engaging a thread on the end of the shaft 22,

and bearing against a washer, 36, which fits against the spring 34.WVhen, in the movement of the blank 18 by the feed-rolls, its end isbrought against the stop 16, the induced resistance overcomes thefrictional contact due to the spring 34, and the further movement of thefeed-rolls is arrested during the cutting and punching of the nail.

In order to admit of end movement of the lower feed-roll, 20, toaccommodate lateral variations in the blank 18, either as to width oralignment, a spring, 37, is fitted upon the feed-roll shaft 23, betweena fixed collar, 39, thereon and a loose washer, 38, adjoining one of itsbearings. Lateral pressure upon the flange 21, caused by inequalities inthe blank, will force the lower feed-roll, 20, outwardly for asufficient distance to admit of the passage of the obstructing portionof the blank, and the spring 37, being coincidently compressed, willthereafter return the shaft 23 and pulley 20 to normal position. The finished nails are discharged as formed from the former 13 by the end of adischarge-rod, 40, which is reciprocated transversely to the former 13bya double-armed lever, 41, pivoted by a pin, 42, to the frame 1, andcoupled at its lower end to the discharge-rod 40. The upper end of thelever 41 carries a pin or roller, 43, which is pressed up to the faceofa cam, 44, on the driving-shaft 3 by a spring, 45, bearing against thelower arm of the lever 41, the cam 44 thus acting to move the end of thedischarge-rod 40 toward and from the face of the former 13 at eachrevolution of the driving-shaft.

Thefixed and movable dies 10 and 9, before described, are adapted toform a single-point ed nail, 46, as shown in Fig. 11, and for theproduction of the double-pointed nail 47 (shown in Fig. 12) they aremodified, as illustrated in Figs. 7 to 10, inclusive. In suchcase thepunch 12 of the movable die 9, in lieu-of having an angular or V-shapedface, as before described, is formed with a correspondinglyshapedrecess, and a corresponding angular face -is formed upon the tongue 14of the fixed die 10. The fixed and movable dies are also reversed inposition upon the machine-that is to say, their'ends having thepunchandtongue, respectively, are placed nearest the. feed-rolls 19 and20. The upper surface of the tongue 14 then occupies the positionandperforms the function of the track 17 in the formercase, and a stop, 48,is formed at the op posite end of the former 13, as the equivalent ofthe stop 16 before employed, the operation of the several members beingsimilar to that performed in cutting and bending a singlepointed nail. I

In order to obviate risk of breakage of the machine in case it shouldbecome choked, as might occur from failure to discharge the nails underthe continued feed of the blank,'the

driving-pulley4 is fitted loosely upon the driving-shaft 3, and isadapted to rotate the same by frictional contact, as in the case of thefeedroll pulley 33, before described. A spring, 49, is compressed withina recess on the pulley 4, by a nut, 50, engaging a thread on thedriving-shaft, and bearing on a washer, 51, fitting against the spring49, which is compressedso as to induce only suflicient friction to cutand. puncha single thickness of the blank. Upon the choking of the diesthe pulley 4 will slip. upon the shaft and the rotation of the machinewill be arrested without damage to the parts.

In operation, the blank 18 is led from a suitable reel, upon which it iscoiled, to and between the feed-rolls 19 and 20, and the spring 28 isscrewed down sufficiently to effect the proper feed of the blank to thedies. When the end of the blank abuts; against the stop 16, (or 48, asthe case may be,) the feed is stopped by thepulley 33 slipping on thefeed-shaft 22, and by the descent of the movabledie '9; a nail is cutand bent to the desired form. :By the movement of the dischargerod 40,the finished nail is pushed oif the former 13, the feedrollsresumetheirrotation, and the blank. is moved forward for another operation.

I claim as. my inventioni and desire to secure by Letters-Patent 1. Ina-nail-machine, a cuttingand bending die, 9, substantially as setforth-to wit, having ,an angular recess, 11, in its face correspendingin form with the desired outer 1ongitudinal outline of the nailto beout, with a cutting-edge located at one end of said recess,

and a cutting and bending punch, 12, located 7 at the'other end thereof.
